The Home All Of Us Have Seen
On a road of black lies a house
The block quiet as a mouse
All but one of the others
Never knew children and mothers
That one long has been foreclosen
And this one life has chosen
The home painted blue and green
It's a home all of us have seen
Few who live there beyond it motion
And tell me if you have a notion
What it is with roof of dome
Tell me now what is this home?

Swinging At The Park Riddle
Which swings faster? And more importantly, why?
Hint:
The speed at which a pendulum swings is called the period and given by the equation:
2 x pi x square root of (length of rope from fulcrum to Center of Mass divided by gravity)
Since gravity is constant, the only thing that effects the period is the length of rope. In the above scenario, you assume the man is taller then the child. Therefore his center of mass is higher. This makes the distance between the fulcrum to the center of mass shorter then for the child. The man swings faster. Did you answer this riddle correctly?

Cut Through Evil
I cut through evil like a double edged sword, And chaos flees at my approach. Balance I single-handedly upraise, Through battles fought with heart and mind, Instead of with my gaze.

Hint:
Weary Of Battle Riddle
I'm by nature solitary, scarred by spear and wounded by sword, weary of battle. I frequently see the face of war, and fight hateful enemies; yet I hold no hope of help being brought to me in the battle, before I'm eventually done to death. In the stronghold of the city sharp-edged swords, skilfully forged in the flame by smiths, bite deeply into me. I can but await a more fearsome encounter; it is not for me to discover in the city any of those doctors who heal grievous wounds with roots and herbs. The scars from sword wounds gape wider and wider; death blows are dealt to me by day and by night.

Hint:
Counterfeit Coins Riddle
You are given eight coins and told that one of them is counterfeit. The counterfeit one is slightly heavier than the other seven. Otherwise, the coins look identical. Using a simple balance scale, how can you determine which coin is counterfeit using the scale only twice?
Hint:
First weigh three coins against three others. If the weights are equal, weigh the remaining two against each other. The heavier one is the counterfeit. If one of the groups of three is heavier, weigh two of those coins against each other. If one is heavier, its the counterfeit. If theyre equal weight, the third coin is the counterfeit.

Hint:
Fastest Horse Riddle
They can only race 5 horses at once, so what is the fewest number of races they can conduct to find the 3 fastest horses?
Hint:
First you divide the 25 horses into 5 groups of 5. You conduct the 5 races and take all of the fastest horses in those races and have a race with them, giving you the fastest horse. Then you take the remaining 24 horses (excluding the fastest) and remove the 4th and 5th horses in the first set of 5 races (since they definitely have 3 horses faster than them), leaving you with 14 horses. Next you can remove all of the horses that were beat in the preliminary race by the horses that got 4th and 5th in the championship race, leaving you with 8 horses. Finally, you can remove the horses that remain that lost to the 3rd place horse in the final race in the preliminary race and the horse that got 3rd in the preliminary to the horse that got 2nd in the championship race, leaving you with 5 horses.
You can then run a final race where the 1st and 2nd place horses are the 2nd and 3rd fastest. Then you know the 3 fastest horses. Did you answer this riddle correctly?
YES NO

Rope Burn Riddle
Hint: You can light multiple ends and/or multiple ropes at the exact same time.

When the first rope burns out, there will be 30 minutes left on the second rope. So then, light the other end of the second rope, and the rest of it will burn out in 15 minutes. 30 + 15 = 45 minutes.
